The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/c931242dba631dfb1e2b63e84550e5859c07788d commit c931242dba631dfb1e2b63e84550e5859c07788d Author: Justin Novosad <junov@chromium.org> Date: Wed Jul 25 15:08:03 2018 Code cleanup: HTMLCanvasElement::CopiedImage This change removes the now useless copied reference that is retained by HTMLCanvas. This was useful back when the code used SkBitmap, which did not have copy-on-write semantics.

fserb@: You own this now. I have written up a CL that implements this on top of ToT. It compiles, but I have not had time to test and debug the issue. The WIP CLs are here: * chromium: https://chromium-review.googlesource.com/c/chromium/src/+/1150412 * WebGL conformance tests: https://github.com/KhronosGroup/WebGL/pull/2496
